How to fix a PC whose Bluetooth wont detect / connect to other devices

In our previous guide on Windows PC radio issues & fixes, we discussed How to fix Wi-Fi disabled by Windows Mobility Center (see https://journal.hovatek.com/how-to-fix-wi-fi-disabled-by-windows-mobility-center/ ) . In this guide, we’ll be looking at a common Bluetooth headache; which is problems detecting or connecting to other Bluetooth devices. We’ll be discussing common causes and working fixes to apply when experiencing such.

What could cause a Windows PC’s Bluetooth not to detect or connect to other Bluetooth devices?

When faced with Bluetooth detection or connection problems, possible causes are:

  • Bluetooth is not on: Its possible the PC’s Bluetooth is off
  • Too many paired devices: The PC or other Bluetooth device might have too many devices on its paired list
  • Bluetooth is set to hidden:  The PC’s Bluetooth might have been set to hidden / stealth mode
  • Devices aren’t paired: The devices need to be paired for a transfer to occur
  • Bluetooth Connection notification is off: You might not get a Bluetooth connection request if connection alert is disabled
  • PC doesn’t support Bluetooth: Check the PC’s specifications to be sure it supports Bluetooth
  • Bluetooth driver problems: The PC’s Bluetooth drivers might be missing, corrupted or outdated
  • Damaged Bluetooth radio: The Bluetooth radio might have encountered a hardware problem
  • Out of range: Proximity is very important in Bluetooth communication. Ensure the devices are within detection range
  • Wrong Bluetooth connection mode: Its possible the Bluetooth isn’t set to Send or Receive mode as appropriate

I dont think HP 2000 has bluetooth integrated. It supports Bluetooth but doesn’t have. You might need to use an external bluetooth USB stick.
